RNA cytidine acetyltransferase

Gene

nat10

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

RNA cytidine acetyltransferase with specificity toward both 18S rRNA and tRNAs. Catalyzes the formation of N4-acetylcytidine (ac4C) at positions 1297 and 1815 in 18S rRNA. Required for early nucleolar cleavages of precursor rRNA at sites A0, A1 and A2 during 18S rRNA synthesis (PubMed:25402480). Catalyzes the formation of ac4C in serine and leucine tRNAs. Requires the tRNA-binding adapter protein tan1 for full tRNA acetyltransferase activity but not for 18S rRNA acetylation (By similarity).UniRule annotationBy similarity1 Publication
